RC6432F2371CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2371CS is a 2.37 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film resistor features moisture resistance and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with 932 units available in inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. Alternative sources provide design flexibility, supply chain redundancy, and access to parts with extended certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2371CS is determined by strict equivalence across the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 2.37 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Maintain or Exceed):

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria. Differences in physical dimensions (length, width, height) within the 2512 package specification, packaging format (Tape & Reel vs. bulk), and extended certifications (such as AEC-Q200) do not affect functional substitutability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F2371CS (Samsung Electro-Mechanics): Primary choice for new designs. Active product status ensures long-term availability and manufacturer support. Moisture-resistant thick film construction provides reliability in standard industrial and consumer applications. Suitable for general-purpose circuit applications where automotive qualification is not required.

CRCW25122K37FKEG (Vishay Dale): Recommended as primary substitute. Active product status with higher inventory availability (2353 units). Includes AEC-Q200 automotive qualification, making this part suitable for automotive and mission-critical applications. Tape & Reel packaging supports high-volume manufacturing processes. Electrical and thermal characteristics are identical to the main part.

ERJ-1TNF2371U (Panasonic Electronic Components): Available as secondary substitute with highest inventory level (8539 units). Includes AEC-Q200 automotive qualification. Product status is "Not For New Designs," indicating this part is in mature phase with no active development. Suitable only for replacement or legacy system applications where existing designs already specify this part number. Not recommended for new circuit designs.

Frequently Asked Questions (FAQ)

Q: Can CRCW25122K37FKEG be used as a direct replacement for RC6432F2371CS?

A: Yes. Both parts share identical electrical specifications (2.37 kOhms, ±1%, 1W), temperature characteristics (±100 ppm/°C, -55°C to 155°C), package type (2512), and compliance status (ROHS3, REACH Unaffected, MSL 1). The CRCW part includes additional AEC-Q200 automotive certification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the packaging formats listed?

A: RC6432F2371CS packaging format is not specified in the provided data. CRCW25122K37FKEG and ERJ-1TNF2371U are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Packaging format affects handling, storage, and assembly procedures but does not impact electrical performance or physical fit within the 2512 footprint.

Q: Why is ERJ-1TNF2371U marked "Not For New Designs"?

A: This product status indicates the part is in end-of-life phase. The manufacturer is not actively developing or promoting this part for new applications. While the part remains functionally equivalent and available in inventory, it should be used only for replacement or legacy system maintenance. New circuit designs should specify RC6432F2371CS or CRCW25122K37FKEG.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within the 2512 package specification. RC6432F2371CS: 6.30mm L × 3.20mm W, 0.66mm height. CRCW25122K37FKEG: 6.30mm L × 3.15mm W, 0.70mm height. ERJ-1TNF2371U: 6.40mm L × 3.20mm W, 0.70mm height. These variations remain within standard 2512 package tolerances and do not affect PCB footprint compatibility or circuit performance.

Q: Which part should be selected for automotive applications?

A: CRCW25122K37FKEG is the recommended choice for automotive applications due to active product status and AEC-Q200 qualification. ERJ-1TNF2371U also carries AEC-Q200 certification but is marked "Not For New Designs." RC6432F2371CS does not include automotive certification and should not be specified for automotive designs unless the application does not require AEC-Q200 compliance.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This classification applies to all three parts and means they can be stored at standard ambient conditions without desiccant packaging or controlled humidity environments.
